The contractor would like to install the HVAC equipment although the roof is not on the building yet. It would seem to me that as long as the contractor protects the equipment from moisture and contaminents this should still be in compliance with LEED requirements. They are not planing on using the equipment. Is there anything I am missing or should warn the contractor about?
As long as the equipment is well protected, I can't think of any reason why this strategy would not be ok.
